Because the superhydrophobic surfaces have a water contact angle exceeding 150 degrees and a sliding angle below 5 degrees, they can be applied to various fields with anti-wetting, self-cleaning, anti-fogging, anti-frosting, and anti-icing. However, they are limited to a practical application due to poor mechanical durability and opaque nature by their surface microstructures. In this study, we describe clearly visible superhydrophobic surfaces with improved mechanical strength via a simple spray coating. We modified polydimethylsiloxanes to be more hydrophobic and combinative through hydrosilylation with functional acrylate groups. We also made the surface rough with fluorinated silica nanoparticles. As a result, the coated surfaces exhibited high water repellency and low contact angle hysteresis. In particular, our superhydrophobic surfaces had a strong mechanical strength, and a transparency to be clearly visible the under side pictures. |
